WINDOW SHADE ADJUSTING DEVICE Filed April 1, 1929 2 Sheets-Sheet 2INVENTOR ATTORNEY Patented Sept. 6, 1932 SAMUELJASGUR, or BROOKLYN, mw(YORK WINDOW SHADE ADJUSTING DEVICE Application filed April 1,

My invention relates to adjustable window shades and refers particularlyto devices having two vertical channel shaped members andadapted for theraising and lowering of win dow shades or curtains. I

The rollers carrying window shades, or curtains, are usually attached toopposite sides of a window frame and hence are not capable of beingraised or lowered.

This fixed position of the curtain roller is objectionable as theunrolled curtain prevents the'free access of air when the upper windowsash is lowered, and as it is frequently desirable to obtain free accessof air through the upper open portion of the window, while usingthe'curtain as a screen only for the unopen portion, it is evident thata device which will accomplish this'result 1s of great value andconvenience. V

The device of my invention produces this desirable result in aneffective manner as will be evident upon a consideration of myspecification and its accompanying drawings.

In the accompanying drawings illustrating one form of the device of myinvention, similar parts are designated by similar numerals.

having the bottom 10, the sides 11 and 12, r

the top 13 and carryingtheupper and the lower sash 15.

Attached to the inner face of the frame side 11 is a channel-shapedmember 16 having a longitudinal slot 17- therein formed. by a cut-outand inwardly bent portion 18. The said channel-shaped member 16 isattached to the frame side 11 by means of ascrew passing through a holein its foot 19- and is attached to the frame top 13by means' of a screwpassing through its angularly positioned head 20. 5 a

A bushing 21 is inserted through an open-i ing in the lower'portion ofthe member 16, within which is a revoluble shaft 22 carry ing a-toothedwheel'23 within the member 16 and a knurled wheel 24.

sash 14 Vertically slidable'within the slot 25 of V the member 16 is arod 26, having a knurled knob 27 exterior ofthe device, and a downwardlyprojecting-pointed member 28 capa teeth :of' the sprockets of the wheel23. p v 5 'Attachedto the inner face of the frame side 12 is achannel-shaped member 29 having a vertical slot, similar to thechannelshaped member 16 and its slot, -Within'thelower portion of themember 29-is a spr0ck-j80 et wheel 30 revoluble upon the studshaft 31and spaced from the face of-the member 29 by the spacer 32. A lock nut33, retains these elementsin position. 1 The two upper'portions of-thechann eL shaped members'16 and 29 are connected by two revoluble rods34' and 3 4 slidable with V in thesleeve 3'5 and: maintained in desiredposition therein by the set-screws 36, 36'.

Within the channel shaped member 29 is a curtain support 46 to which thechain 40 is attached, the upper portion 47 of the support being bent andextending outwardly through the longitudinal slot of member 29. Themember 46 has the two round openings 48 and 49 and the angular opening50.

The end carriers of a spring-operated curtain 51 are placed in theopenings 43 and48 ,ed doubleprong member 55, each pair of oppositeprongs, being capable of supporting a drapery support 56.-

The operation of my device is'as follows, assuming that the device isinits utmost up ward position and it is desired to lower the upper sash14 and'to lower the device accordingly The knob 27 is raised thusallowing the revolution of the sprocket 23. The knob 24 is thenrevolved, which revolves the sprock-. et 23, movingthe chain 39,revolving the sprocket 37, the rods 34 and 35 and the sprocket 38,moving the chain and revolving the sprocket 30. It will thus be seenthat the two chains 39 and 40 move in unison, carrying the curtaincarriers 41 and 46 withftheir attached curtains. The revolution 'of theknob 24, therefore, moves the curtains up or down to the desiredposition and the lowering of the knob 27 retains themin the desiredposition. If iteis desired that draperies be; moved at the same time,the

members 53, 53 are employed as above described. The extended members 42and 47 prevent the accidental spring unrolling of the shades,'as thewooden cross-piece of the extremity of the shade can notlpass betweenthe rolled shade and the members 42 and 47.

The modified form of. curtain carrier shown in Figure 10' comprises achannelshaped member having an acute-angled member 61 which isverticallyslidable over the inwardly extended member 18 of the channel guide 16,the memberl18 thus acting as a guide for the vertical movement of thecurtain carrier. I

jIt willthus be seenthat my device presents aneasily operative means forraising or lowering a shade, or curtain, roller, to a de'-' siredposition within a window frame.

shape, number, arrangement or material of parts as shown and describedas these are given simply'as a means for clearly describing the deviceof my invention. 7
